Imaging scans following treatment for diffuse large B-cell lymphoma do little to help detect a relapse, according to a Mayo Clinic study.The overwhelming majority of patients with this aggressive lymphoma already have symptoms, an abnormal physical exam or an abnormal blood test at the time of relapse. Lead author Carrie Thompson, M.D., a Mayo Clinic hematologist says,“Our results were surprising because the current standard-of-care is to include scans for the follow-up of this disease.We found that scans detected relapse in only a handful of patients who didn’t have any of those other signs or symptoms.” The findings will be presented at the American Society of Clinical Oncology annual meeting May 31-June 4 in Chicago.
